JANTX1N5314-1

Current Regulation - Diodes, Transistors Overview

The JANTX1N5314-1 is a current regulator diode manufactured by Microchip Technology, belonging to the military-grade 1N5283-1 through 1N5314-1 series. It provides a regulated current of 5.17 mA with a maximum power dissipation of 500 mW and a breakdown voltage of 100 V. The device utilizes a DO-7 axial-leaded package for through-hole mounting. Qualified per MIL-PRF-19500/463, it features high source impedance and an internal metallurgical bond connection within a larger active die element designed for unique current limiting functions.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation over a broad voltage range as a counterpart to Zener diodes.
• Features high source impedance for effective current control.
• Utilizes a double-plug internal bond connection with a larger active die element.

Current Regulation - Diodes, Transistors Applications

• Current limiting circuits in electronic systems.
• Constant current sources requiring broad voltage range operation.
• Military and aerospace applications requiring MIL-PRF-19500/463 qualification.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix to confirm the exact qualification level and package type. Ensure compatibility with MIL-PRF-19500/463 standards if required for the application. Confirm RoHS status, as commercial versions may differ from qualified levels. Check for any product change notifications that might affect specifications or manufacturing location before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a constant current source is needed across a wide voltage span rather than voltage regulation. Compare the 5.17 mA output against other series members like the 1N5313-1 (4.7 mA) or 1N5312-1 (4.29 mA) to match circuit requirements. Consider the DO-7 package size constraints and through-hole mounting needs versus surface mount alternatives like the UR series.

Current Regulation - Diodes, Transistors Part Context

This part is part of the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. The series offers a selection of currents from 0.22 mA to 4.7 mA in standard 10% tolerances. The JANTX1N5314-1 specifically represents the higher current end of the standard axial-leaded options available in military qualification levels including JAN, JANTX, JANTXV, and JANS.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTX series current regulators such as JANTX1N5313-1 or JANTX1N5312-1 if different current values are acceptable. Commercial equivalents like 1N5314-1 are available but lack military qualification. Surface mount replacements include the JANTX1N5314UR-1 in the DO-213AB package.
